3. Hazards Identification

   Irritating to eyes. Flammable. Harmful by inhalation, respiratory system and skin. May cause sensitisation by inhalation. Contains isocyanates.

4. First Aid Measures

   General

   In all cases of doubt or when symptoms persist, seek medical attention. Never give anything by mouth to an unconscious person.

   Inhalation

   Remove patient to fresh air. Keep warm and at rest. Seek medical advice.

   Ingestion

   Do not induce vomiting because of risk of aspiration into the lungs. If aspiration is suspected obtain immediate medical attention.

   Skin

   Remove contaminated clothing. Wash the skin immediately with soap and water. Do not use solvents to clean skin. Seek medical attention if irritation persists.

   Eyes

   In case of contact with eyes, rinse immediately with plenty of water and seek medical advice (S26).

5. Fire Fighting Measures

   Suitable Extinguishing Media

   Foam, dry powder, carbon dioxide. In case of larger fires, water / spray mist may be used. Do not use water jets.

   Exposure Hazards

   In the event of a fire, may produce toxic vapour and fumes.

   Protective Equipment

   Full face positive pressure breathing apparatus and full protective clothing.

6. Accidental Release Measures

   Personal protection

   Remove all sources of ignition. Full face positive pressure breathing apparatus and full protective clothing.

   Environmental Precautions

   Contain and cover any spillage immediately with sand, earth or other suitable absorbent material. Prevent ingress into water courses or sewers.

   Clean Up Methods

   Transfer absorbent material to a suitable waste container. Do not seal. Keep damp and in open air for 7 days. Dispose of in accordance with local and national regulations.

7. Handling and Storage

   Handling

   Avoid contact with skin and eyes. Ensure adequate ventilation when spraying to maintain atmospheric levels in accordance with exposure limits.

   Storage

   Keep containers tightly closed and dry in a well ventilated area away from heat and direct sunlight. Store in accordance with current regulations for the storage of flammable materials. Store between 5-25°C.

8. Exposure Controls and Personal Protection

   Engineering Measures

   Positive exhaust ventilation (flameproof if necessary) or natural ventilation that maintains atmospheric level in accordance with exposure limits.

   Personal Protective Equipment

   Respiratory

   In the absence of exhaust or natural ventilation that maintains atmospheric concentration in accordance with the exposure limits, self contained airline breathing apparatus should be worn.

   Skin

   Chemical proof suit and footwear should be worn.

   Eyes

   Goggles should be worn.

   Hand

   Chemical resistant rubber gloves - change frequently as required.

10. Stability and Reactivity

    Stable under recommended storage and handling conditions.

    Conditions to Avoid

    Contamination with water. Excessive build up of vapour.

    Materials to avoid

    Acids, amines, waters, alcohols, oxidising agents, heavy metals.

    Hazardous Decomposition Products

    Toxic fumes including hydrogen cyanide and carbon monoxide may be generated.

    Hazardous Polymerization

    May occur if held at temperatures in excess of 80°C or in contact with amines, water, alcohols, acids or heavy metals.

11. Toxilogical Information

    Skin

    Repeated skin contact will cause defatting, leading to irritation and possibly dermatitis.

    Eyes

    Severe eye irritant.

    Respiratory

    High concentrations can cause headaches, vomiting and narcotic effects. Respiratory sensitisation may occur as a result of long term exposure to isocyanate vapours or short term exposure to excessive vapour concentrations.

    Ingestion

    May result in nausea, dizziness, irritation of the gut.

12. Ecological Information

    Ecotoxicity

    Some components are expected to exhibit high mobility in soil and could leach to ground water.

    Bioaccumulative Potential

    If remaining near to the surface of soil, some components will evaporate slowly and may photo-oxidise and gradually degrade. Degradation in the soil will occur over an extended period of time.

    Appraisal

    All necessary precautions should be taken to prevent entry of the components into the soil, water or atmosphere.

13. Disposal Considerations

    Dangers

    Drum pressurisation can occur as a result of reaction with water or atmospheric moisture or if heated. Toxic fumes or vapours may be generated on incineration.

    Disposal of substance/preparation

    Small quantitiers of isocyanate may be decontaminated using an approved technique.

    Disposal of Packaging

    Drums may be decontaminated by an approved procedure.
